RESUMO
Key Clinical Message: Posterior Reversible Encephalopathy Syndrome, typically characterized by parieto-occipital vasogenic edema, can present atypically, as a bilateral symmetrical vasogenic edema in the basal ganglia, featuring the called "lentiform fork sign." Prompt recognition of such variations is crucial for accurate diagnosis and tailored management, highlighting the complexity of this syndrome's manifestations. Abstract: Posterior Reversible Encephalopathy Syndrome (PRES) manifests as transient neurological symptoms and cerebral edema, commonly associated with immunosuppressive drugs (ISDs) in transplant recipients. ISDs can lead to endothelial dysfunction and compromise the blood-brain barrier. Typically, PRES exhibits identifiable MRI patterns, often demonstrating vasogenic edema in the bilateral parieto-occipital white matter. Identifying unique presentations, such as the recently observed "lentiform fork sign," commonly seen in uremic encephalopathy, emphasizes this syndrome's broad spectrum manifestations. A 19-year-old male, who underwent bilateral lung and liver transplantation, experienced a bilateral tonic-clonic seizure of unknown onset 47 days post-surgery. MRI findings revealed an unconventional PRES pattern, featuring the "lentiform fork sign" as bilateral symmetrical vasogenic edema in the basal ganglia, surrounded by a hyperintense rim outlining the lentiform nucleus bilaterally. Subsequent management, including ISD modification and magnesium supplementation, resulted in clinical and neuroimaging resolution. An almost complete clinical and radiological resolution was achieved after 14 days. The occurrence of PRES in transplant recipients highlights the intricate interplay among ISDs, physiological factors, and cerebrovascular dynamics, potentially involving direct neurovascular endothelial toxicity and disruption of the blood-brain barrier. Neuroimaging plays a pivotal role in diagnosis. The distinctive "lentiform fork sign" was observed in this patient despite the absence of typical metabolic disturbances. Management strategies usually involve reducing hypertension, discontinuing ISDs, correcting electrolyte imbalances, and initiating antiseizure drugs if necessary. Identifying the presence of the "lentiform fork sign" alongside typical PRES edema in a patient lacking renal failure emphasizes that this manifestation is not solely indicative of uremic encephalopathy. Instead, it might represent the final common pathway resulting from alterations in the blood-brain barrier integrity within the deep white matter. Understanding such atypical imaging manifestations could significantly aid earlier and more precise diagnosis, influencing appropriate management decisions.
RESUMO
Background: Care partners of persons living with dementia and their care-recipient have low levels of physical activity. Mobile applications have demonstrated effectiveness in promoting physical activity among older adults. The purpose of this study was to explore the perceptions of spousal care partners of persons with dementia and their care-recipient on the design and content of a mobile application intended to promote physical activity.Methods: Semi-structured interviews were conducted with 14 care partners and their care-recipient. After the interviews were transcribed verbatim, thematic analysis was performed.Results: Four themes emerged from the participants' responses related to the design and content of a mobile application to promote physical activity: 1) exercise preferences and habits, 2) barriers to exercise, 3) motivations for exercise, and 4) mobile application preferences and supportive features.Conclusion: Findings lay the foundation for designing an effective user-friendly mobile application to promote physical activity that caters to the diverse needs, preferences, and challenges among spousal care partners of persons with dementia and their care-recipient.
RESUMO
BACKGROUND: Hair transplantation is a widely performed cosmetic procedure for hair restoration. While generally safe, it carries the risk of complications, including recipient site necrosis (RSN). RSN is a rare but serious complication. This study aims to conduct a detailed analysis of 18 patients who had necrosis in the recipient area after hair transplantation. METHODS: A retrospective review of medical records was conducted on 18 consulted patients who developed RSN following hair transplantation between 2017 and 2023. Data collected included patient demographics, medical history, surgical details, treatment modalities, and outcomes. Treatment involved surgical intervention (debridement), and conservative measures (wound care) in all cases. RESULTS: The mean age of patients was 36.06 years (range: 22-48). The most common risk factors identified were smoking 66.7% (n = 10), hypertension 20% (n = 3), and diabetes mellitus 13.3% (n = 2). All patients (n = 18) underwent single-session hair transplantation using the follicular unit excision technique, and an average of 3899.44 ± 93.76 follicular units were transplanted. Outcomes such as scarring and graft failure occurred in all patients. CONCLUSION: The presented study is the largest complication series in the literature. RSN is a rare but significant complication of hair transplantation. Identifying and managing risk factors, such as smoking, diabetes and hypertension, is crucial for prevention. Early recognition and prompt treatment are essential for optimal outcomes. While conservative management is often successful, surgical intervention may be necessary in severe cases.

RESUMO
Introduction: BK polyomavirus-associated nephropathy (BKPyVAN) is a significant complication in kidney transplant recipients (KTRs), associated with a higher level of plasmatic BK polyomavirus (BKPyV) replication and leading to poor graft survival. Methods: We prospectively followed-up with 100 KTRs with various degrees of BKPyV reactivation (no BKPyV reactivation, BKPyV-DNAuria, BKPyV-DNAemia, and biopsy-proven BKPyVAN [bp-BKPyVAN], 25 patients per group) and evaluated BKPyV-specific T cell functionality and phenotype. Results: We demonstrate that bp-BKPyVAN is associated with a loss of BKPyV-specific T cell proliferation, cytokine secretion, and cytotoxic capacities. This severe functional impairment is associated with an overexpression of lymphocyte inhibitory receptors (programmed cell death 1 [PD1], cytotoxic T lymphocyte-associated protein 4, T cell immunoreceptor with Ig and ITIM domains, and T cell immunoglobulin and mucin domain-containing-3), highlighting an exhausted-like phenotype of BKPyV-specific CD4 and CD8 T cells in bp-BKPyVAN. This T cell dysfunction is associated with low class II donor-recipient human leukocyte antigen (HLA) divergence. In contrast, in the context of higher class II donor-recipient HLA (D/R-HLA) divergence, allogeneic CD4 T cells can provide help that sustains BKPyV-specific CD8 T cell responses. In vitro, allogeneic HLA-mismatched CD4 T cells rescue BKPyV-specific CD8 T cell responses. Conclusion: Our findings suggest that in KTRs, allogeneic CD4 T cells can help to maintain an effective BKPyV-specific CD8 T cell response that better controls BKPyV replication in the kidney allograft and may protect against BKPyVAN.
RESUMO
Pregnancy losses negatively affect the cattle industry, impacting economic indices and consequently the entire production chain. Early embryonic failure has been an important challenge in the embryo industry because proper identification of embryo death at the beginning of gestation is difficult. This review aimed to provide a better understanding on reproductive failure and the relationship between early embryonic loss and different reproductive biotechniques. This review also considers insights and possible strategies for reducing early embryonic loss. The strategies addressed are as follows: i) great impact of rigorous embryo evaluation on reducing embryo losses; ii) selection of recipients at the time of transfer, taking into account health and nutritional status, and classification of the corpus luteum using ultrasound, either in area or vascularization; and iii) paternal effect as one of the factors that contribute to pregnancy losses, with a focus on embryo transfer.
RESUMO
BACKGROUND: Whether solid organ transplant (SOT) can be safely performed in recipients with ongoing SARS-CoV-2 infection is still a debated question. METHODS: A systematic review of the literature on recipients with ongoing SARS-CoV-2 infection at the time of surgery and the associated outcomes. RESULTS: From 29 studies, we identified 54 recipients; their median age was 47.5 years, and over half (23/54,54.85%) were affected by fewer than two comorbidities. Kidney was the most common transplanted organ (24/54,44.4%). SOT was performed without knowing the ongoing infection in 11.1% (6/54) of patients. On average, 16.1 (SD 23.2) days elapsed between SARS-CoV-2 infection and SOT, with a mean Ct value at diagnosis and transplantation of 29 and 31.9, respectively. Most patients (25/39,64.1%) had received previous COVID-19 vaccinations. Twenty-four patients (45.3%) received an anti-SARS-CoV-2 therapy. Ten patients (18.5%) required oxygen support, while seven (13.7%) were admitted to the intensive care unit. There were two reported cases (3.7%) of all-cause death, while there were no cases of COVID-19-related death. CONCLUSIONS: Deliberate SOT of recipients with ongoing SARS-CoV-2 is performed worldwide in candidates of non-lung transplant who are fit, immunized against the virus, and displaying a non-severe disease course. No COVID-19-related deaths were recorded.
RESUMO
BACKGROUND/PURPOSE: Living donor liver transplantation (LDLT) is vital for pediatric end-stage liver disease due to organ shortages. The graft-to-recipient weight ratio (GRWR) preoperatively measured predicts the outcomes of LDLT. We typically target between 0.8 and 3.0-4.0%, but the ideal GRWR remains controversial. We compared the outcomes of LDLT according to the GRWR to examine whether the criteria could be expanded while ensuring safety. METHODS: We retrospectively reviewed 99 patients who underwent LDLT in our department by dividing them into three groups according to their GRWR: Group S, with GRWR values lower than the normal range (GRWR < 0.8%); Group M, with GRWR values in the normal range (GRWR ≥ 0.8 to < 3.5%); and Group L, with GRWR values above the normal range (GRWR ≥ 3.5%). RESULTS: In Groups S and L, 46.2 and 44.4% of patients underwent splenectomy and delayed abdominal wall closure, respectively. After these intraoperative adjustments, there were no significant differences between the groups in 5-year patient survival, 5-year graft survival, or the occurrence of post-transplantation thrombosis. CONCLUSION: When the GRWR is beyond the normal threshold, the risk of complications associated with graft size might be reduced by adjustments to provide appropriate portal blood flow and by delayed abdominal wall closure.

OBJECTIVES: This study aims to examine and synthesise the views and experiences of women, donors, recipient mothers and healthcare professionals regarding human milk donation or sharing. METHODS: The Joanna Briggs Institute (JBI) meta-aggregative approach to systematic reviews of qualitative studies was adopted. Six databases, MEDLINE, CINAHL, Embase, PsycINFO, Web of Science and Scopus were searched. English written qualitative studies from database inception to February 2024 were included. The JBI Critical Appraisal Checklist for Qualitative Research was used to appraise the collected research evidence. RESULTS: A total of 629 papers were screened, and 41 studies were included in the review. Six key findings were synthesised. (i) Donors, recipients and their families all benefit from milk donation. (ii) Motivation to receive or donate breast milk. (iii) Awareness and participation are affected by formal vs. informal sharing, mothers' personal experiences and external factors. (iv) Concerns about disease transmission, jealousy, bonding and traits. (v) Challenges encountered by donors, recipient mothers, staff and milk banks (vi) Suggestions for promoting human milk donation. DISCUSSION: Stakeholders of human milk donation, including donors, recipient mothers, healthcare professionals, and human milk bank representatives, face various physical, mental and practical challenges. Informal sharing complements formal donations and contributes to improved breastfeeding rates. Advocacy and education efforts are still needed to increase participation and safety levels. The major limitation of the study is the inadequate search on views of immediate family members.

INTRODUCTION: The imbalance in gut microbiota is contributing to the development and progression of IBS. FMT can improve the gut microbiota, and donor-recipient-matched FMT can help develop individualized treatment plans according to different enterotypes. This study aimed to explore the efficacy of donor-recipient-matched FMT in IBS with predominant diarrhoea (IBS-D) and evaluate its effects on gut microbiota. METHODS: Twenty-seven patients with IBS-D were randomly divided into donor-recipient-matched FMT group (group P), random-donor FMT group (group R), and placebo group (group B). All participants received corresponding FMT treatment after filling in IBS-S, IBS-QoL, GSRS, and HADS questionnaires and having their stool samples collected at 4, 8, and 12 weeks after treatment. The improvement in the symptoms and the changes in the bacterial flora were analysed for three groups. RESULTS: The IBS-SSS, IBS-QoL, GSRS, and anxiety scores of group P were significantly lower after treatment (p < 0.05). The IBS-QoL scores of group R were significantly lower after treatment (p < 0.05). Beta diversity analysis showed that the gut microbiota of group P had an obvious trend of classification after treatment. Seven bacterial genera were related to the differences in the IBS-SSS scores before and after treatment. CONCLUSION: Donor-recipient-matched FMT significantly improved the clinical symptoms, quality of life, and anxiety scores of the patients with IBS-D than random-donor FMT.
RESUMO
Rhabdomyolysis involves significant skeletal muscle injury and destruction, which can be triggered by trauma, intense physical activity, heat, prolonged immobility, certain medications, and endocrine disorders. Rhabdomyolysis in renal transplants can be more complicated, and the prognosis is not well known, especially in the context of coexisting rejection. We present a case of rifampicin-induced rhabdomyolysis with superimposed acute cellular rejection in a kidney transplant patient.
RESUMO
Background: Syndrome of inappropriate anti-diuretic hormone secretion (SIADH) is associated with strongyloidiasis. Herein, a rare case of severe SIADH secondary to disseminated strongyloidiasis in a kidney transplant recipient is reported. Case presentation: A case involving a 43-year-old male kidney transplant recipient with severe disseminated Strongyloides stercoralis infection is reported. The patient was a construction worker with a history of consuming undercooked yellow eel and sashimi. On admission, the patient presented with poor appetite, nausea, vomiting and diarrhea. Laboratory investigations revealed persistent significant hyponatremia and low serum osmolality, confirming the diagnosis of SIADH. S. stercoralis was detected in the stool and bronchoalveolar lavage fluid. He was treated with empirical albendazole because S. stercoralis was detected in the stool; however, his symptoms and hyponatremia did not improve until ivermectin was administered, after which SIADH resolved quickly. Conclusion: This case suggests that S. stercoralis infection should be included in the differential diagnosis when a kidney transplant recipient presents with gastrointestinal symptoms and SIADH. In such situations, pre- or post-transplant screening for S. stercoralis is needed, and early ivermectin treatment is very important.
RESUMO
This study assessed humoral and T cell-mediated immune responses to the BNT162b2 vaccine in orthotopic liver transplant (OLT) and lung transplant (LUT) recipients who received three doses of the vaccine from March 2021 at our institution. Serum samples were collected 60 days post-second and third dose to quantify antibodies against the spike region of SARS-CoV-2 while whole blood samples were collected to analyze the SARS-CoV-2-specific T-cell response using an IFN-γ ELISpot assay. We enrolled 244 OLT and 120 LUT recipients. The third dose increased antibody titres in OLT recipients (from a median value of 131 after the second dose to 5523 IU/mL, p < 0.001) and LUT recipients (from 14.8 to 1729 IU/mL, p < 0.001). T-cell response also increased in OLT recipients (from 8.5 to 23 IFN-γ SFU per 250,000 PBMC, p < 0.001) and LUT recipients (from 8 to 15 IFN-γ SFU per 250,000 PBMC, p < 0.001). A total of 128 breakthrough infections were observed: two (0.8%) OLT recipients were hospitalized due to COVID-19 and one died (0.4%); among LUT recipients, seven were hospitalized (5.8%) and two patients died (1.7%). In conclusion, the three-dose schedule of the BNT162b2 vaccine elicited both humoral and T cell-mediated responses in solid organ transplant recipients. The risk of severe COVID-19 post-vaccination was low in this population.

Objective: To examine the impact of care-recipient relationship type on mental health burden of caregivers for schizophrenia patients in China, elucidating the underlying mechanisms. Methods: A cross-sectional study was conducted using face-to-face surveys administered to caregivers of patients with schizophrenia in selected communities in Beijing, China. 1,853 samples' data was used. Descriptive statistics, logistic regression models and Sheaf coefficient method were employed to analyze the data. Results: The mental health burden experienced by caregivers of schizophrenia patients has reached a high level, with 66.9% reporting a moderate or severe impact from their caregiving responsibilities. Parents and spouses were the primary providers of care for schizophrenia patients in China. Parent caregivers experienced greater suffering in their caregiving role compared to spouse caregivers, whereas the difference between child caregivers and spouse caregivers was not significant. The factors influencing caregiver's mental health burden vary according to the type of relationship with the care-recipient. For parent caregivers, the mental health burden primarily stems from personal conditions of schizophrenia patients, while for spouse or child caregivers, it mainly arises from family economic conditions. Conclusion: This study reveals that caregivers having different types of care-recipient relationship with schizophrenia patients experience significantly different mental health burdens in Beijing, China, and major influencing factors are distinct according to different care-recipient relationship types.
RESUMO
BACKGROUND: We aimed to analyze the roles of M1 and M2 macrophage infiltration in post-renal transplant antibody-mediated rejection (AMR). METHODS: A total of 102 recipients who underwent renal allotransplant from January 2020 to February 2023 were divided into an immune tolerance group (n = 56) and a rejection group (n = 46). The transplant renal biopsy specimens were harvested by ultrasound-guided puncture. The M1 and M2 macrophages in renal tissues were counted, and the M1/M2 ratio was calculated. The numbers of M1 and M2 macrophages and M1/M2 ratios in patients with different severities of interstitial fibrosis/tubular atrophy (IF/TA) and different degrees of tubulointerstitial inflammatory cell infiltration were compared. The predictive values of M1 and M2 macrophages and M1/M2 ratio for post-renal transplant AMR were clarified. RESULTS: The rejection group had significantly more M1 and M2 macrophages and higher M1/M2 ratio than those of the immune tolerance group (P < 0.05). In the rejection group, infiltrating macrophages were mainly distributed in the glomerular and interstitial capillaries, with M1 macrophages being the predominant type. With increasing severity of IF/TA, the numbers of M1 and M2 macrophages and M1/M2 ratio rose in patients with post-renal transplant AMR (P < 0.05). The numbers and ratio had significant positive correlations with the levels of blood urea nitrogen and serum creatinine (P < 0.05). The areas under the curves (AUCs) of numbers and M1 and M2 macrophages and M1/M2 ratio for predicting post-renal transplant AMR were 0.856, 0.839 and 0.887, respectively. The combined detection had AUC of 0.911 (95% CI: 0.802-0.986), sensitivity of 90.43% and specificity of 83.42%. CONCLUSIONS: Significant macrophage infiltration is present in the case of post-renal transplant AMR, and closely related to the severity of IF/TA and the degree of tubulointerstitial inflammatory cell infiltration.

The bovine embryo production industry has seen significant growth over the past two decades, particularly in the production of in vitro produced embryos. This growth, driven by advancements in cryopreservation, in vitro culture mediums, ovum pick-up (OPU) procedures, ultrasonography devices, and embryo transfer (ET) has been notable. Particularly, ET is crucial for disseminating high genetic merit and amplifying foreign breeds by importing frozen embryos. This retrospective study aimed to assess factors affecting conception per embryo transfer (CPET) in Holstein-Friesian cattle in South Korea from October 2008 to July 2022. We evaluated type of embryo breed, type of embryo production (fresh and frozen; in vitro and in vivo production), recipient conditions including estrus type, corpus luteum quality, parity (nulliparous heifers, primiparous, and multiparous cows), and the daily mean temperature-humidity index (THI) as an index for heat stress. Type of embryo breed and estrus had no significant impact on CPET. However, we observed higher CPET in recipients with good quality corpus luteum, nulliparous heifers, and surrogates receiving fresh in vitro and frozen in vivo embryos. Importantly, CPET was not adversely affected by mild heat stress conditions (up to daily mean THI 76), indicating that using frozen in vivo embryos produced by multiple ovulation embryo transfer and fresh in vitro embryos by OPU-ET can help alleviate the subfertility issues in dairy cattle caused by global warming in Korea.

Introduction: Kidney transplantation from a living donor is the treatment of choice for end- stage kidney disease. Psychological implications of living kidney donation are of great importance, both during preliminary psychiatric assessment and post-donation follow-up. The identification of risk factors worsening the psychological well-being of living kidney donors (LKDs), before and after donation, remains challenging in terms of research. Methods: At the University Hospitals of Geneva (HUG), our clinical observations and practice compelled us to establish post-donation follow-ups for LKDs at 6 months and 1 year. Pre-and post-donation sociodemographic, physical, psychological, and psychiatric data was collected from the medical records of 115 LKDs who underwent a complete physical and psychological evaluation during the period 2011-2018. We tested for any potential association between the variables under study. Results: A qualitative and retrospective analysis of this data highlighted the impact of postoperative factors, such as pain, fatigue, recipient-donor relationship, and fulfillment of donors' expectations, on the post-donation psychological well-being of LKDs. Discussion: With regard to these findings, regular post-donation follow-ups, optimal care of postoperative pain and fatigue, as well as a solid therapeutic alliance with LKDs remain key points for clinicians involved in the dynamic process of living kidney donation.
RESUMO
Donor and recipient human cytomegalovirus (HCMV) seropositive (D+R+) lung transplant recipients (LTRs) often harbor multiple strains of HCMV, likely due to transmitted donor (D) strains and reactivated recipient (R) strains. To date, the extent and timely occurrence of each likely source in shaping the post-transplantation (post-Tx) strain population is unknown. Here, we deciphered the D and R origin of the post-Tx HCMV strain composition in blood, bronchoalveolar lavage (BAL), and CD45+ BAL cell subsets. We investigated either D and/or R formalin-fixed paraffin-embedded blocks or fresh D lung tissue from four D+R+ LTRs obtained before transplantation. HCMV strains were characterized by short amplicon deep sequencing. In two LTRs, we show that the transplanted lung is reseeded by R strains within the first 6 months after transplantation, likely by infiltrating CD14+ CD163+/- alveolar macrophages. In three LTRs, we demonstrate both rapid D-strain dissemination and persistence in the transplanted lung for >1 year post-Tx. Broad inter-host diversity contrasts with intra-host genotype sequence stability upon transmission, during follow-up and across compartments. In D+R+ LTRs, HCMV strains of both, D and R origin can emerge first and dominate long-term in subsequent episodes of infection, indicating replication of both sources despite pre-existing immunity.

BACKGROUND: Systemic inflammatory responses soon after liver transplantation in children can lead to complications and poor outcomes, so here we examined potential risk factors of such responses. METHODS: Data were retrospectively analyzed for 69 children who underwent liver transplantation at a single center between July 2017 and November 2019 through follow-up lasting up to one years. Numerous clinicodemographic factors were compared between those who suffered early systemic inflammatory response syndrome (SIRS) or not. RESULTS: Of the 69 patients in our analysis, early SIRS occurred in 35 [50.7%, 95% confidence interval (CI), 38.6-62.8%]. Those patients showed significantly higher graft-to-recipient weight ratio (3.69 ± 1.26 vs. 3.12 ± 0.99%, P = 0.042) and lower survival rate at one year (85.7% vs. 100%, P = 0.023). Multivariate analysis found graft-to-recipient weight ratio > 4% to be an independent risk factor for early SIRS [odds ratio (OR) 3.8, 95% CI 1.08-13.371, P = 0.037], and a cut-off value of 4.04% predicted the syndrome in our patients, and area under the receiver operating characteristic curve of 0.656 (95% CI 0.525-0.788, P = 0.026). CONCLUSIONS: Graft-to-recipient weight ratio > 4% may predict higher risk of SIRS soon after liver transplantation in children.
